The Brief

A decade of memories, and a home ready for what came next.

Ian and Fiona had lived in their Onehunga home for more than a decade. The kids grew up here. Christmas mornings, school holidays, the lot. As the kids moved out, the house needed to change with them.

They wanted to stay put — and they wanted to age in place. That meant a ground-floor master so they wouldn’t be climbing stairs to bed in twenty years. And while we were at it, Fiona wanted a kitchen she could actually cook and entertain in, not the cramped one they’d been working around for a decade.

The brief: keep the character of the original home, add what was missing downstairs, stay inside a tight budget, and get it through council.

The Outcome

A home that works now, and twenty years from now.

The new ground-floor extension added a full master suite — bedroom, ensuite and a walk-in wardrobe — without ever feeling like an add-on. The detailing, the roof line, the eaves: it reads as one house from the street.

Inside, the new kitchen finally gave Fiona the bench space and storage she’d been after for ten years. Modern appliances, custom cabinetry, room to entertain. The flow between kitchen, living and the new bedroom wing means Ian and Fiona never have to go upstairs unless they want to.

The Transformation

Before & After

Before Onehunga home before ground floor extension — original single-level footprint

The house as we found it — no ground-floor bedroom, no way to age in place without major upheaval.

After Onehunga home after ground floor extension — new master suite seamlessly integrated

New master wing added to the back. From the street, the extension reads as part of the original home.

A ground-floor home extension with a full master suite and a new kitchen — designed to match the character of the original house and let Ian and Fiona age in place.

New single-level addition to the rear of the home, designed and detailed to match the existing roof line, eaves, and exterior cladding so the new and old read as one house.

03

Ensuite Bathroom

Full tiled ensuite with walk-in shower, accessible vanity layout, and clean modern detailing.

Walk-In Wardrobe

Built-in walk-in wardrobe off the master — proper hanging, drawers, and shelving designed around how Ian and Fiona actually use it.

05

New Kitchen

Simon and Joanna of Add Value Renovations planned and completed our en-suite upgrade. We are entirely happy with the finished product and the service and care they provided. We especially appreciated the direct communication with Simon. He is a good man — honest, reliable, and easy to work with. The attention to detail and quality of the finish was outstanding.

We loved working with Simon and the team at Add Value Renovations. Add Value's project manager Tim, and interior designer Joanna, had excellent communication throughout the entire process. The quality of the workmanship was top-notch and they completed our bungalow renovation on time and on budget.

Just wanted to take a moment to express my appreciation for the outstanding work you've done! A ext. renovation done by Add Value was truly a remarkable transformation. The kitchen and bathroom designs are not only aesthetically stunning but also highly functional. It's evident that a lot of thought and care went into every detail.

We have used the services of Add Value Renovations twice over three years, once for bathroom renovations and more recently for our kitchen and deck. The quality of work has always been excellent and any issues that arose were dealt with promptly and professionally.
